1.WASTEWATER CAPITAL IMPROVEMENTS <br />A. <br /> Project Design is under re-evaluation with total project cost approaching $45 <br />million. Discussions with EPA regarding estimated WWTP construction costs <br />increasingfrom $14.6 million to $20.6 million because WWTP site has steeper <br />slopes than predicted. Also, geotechnical borings confirmed the WWTP site has <br />underground voids due to lava tubes. Unknown lava tubes will add additional <br />construction costs should they be encountered during construction. EPA is trying <br />to determine what effects these changes have on the NEPA Environmental <br />Assessment (EA) that was completed last March 2020. County has requested for <br />an extension of the current AOC milestone “Design of WWTP” deadline <br />approved by EPA on May 24, 2021 (using the July 24, 2021 backstop deadline for <br />WWTP Design). <br />• Current Schedule <br />11/04/20: Final AMP approved by SHPD (letter received 11/09/2020). <br />05/24/21: COH submits letter to EPA requesting for time extension to complete <br />WWTP Design. <br />06/14/21: WWTP Land Acquisition via Condemnation (Re-doing Land <br />appraisal) submitted to Court. <br />(We are here) <br />06/24/21: Complete Design of Phase 1 Collection System. <br />08/06/21: Submit Special Permit Application (County acquires land to submit). <br /> 07/24/21: Complete Design of WWTP <br />09/01/21: Advertise for Bid - WWTP and Phase 1 Collection System. <br />12/15/22: Issue NTP for Construction Contract <br />04/18/23: <br /> <br />o Final EA/FONSI was published with OEQC on 03/08/20. Also, the Draft <br />Final AIS was submitted to SHPD on 02/26/20 and SHPD approved as <br />Final AIS on 04/20/20. <br />o Based on SHPD’s review and acceptance of the AIS, an Archaeological <br />Monitoring Plan (AMP) was required. AMP was logged in queue by <br />SHPD on 05/05/20 for review/approval. SHPD approval dated <br />11/04/2020 was received 11/09/2020. <br />o The project is planned for funding with Clean Water State Revolving <br />Funds (CWSRF) loan, County Bonds (CIP), and partially by a federal <br />EPA grant. <br /> <br />B. <br />• The state-level OEQC EA completion is required prior to land purchase for the <br />WWTP/disposal facility. <br />because no federal funds are being used on this LCC project (note: if CWSRF <br />funds are utilized federal cross-cutters are still required). <br />• Initial archaeological, flora and fauna field work completed (11/2020). Section <br />106 and Section 7 consultation by DOH pending final area of potential effect for <br />4 <br /> <br /> <br />
